4. Slide the new element onto the grommet post on
the bottom of the filter header until the element no
longer easily moves up into the filter header. Now
rotate the element (it may take almost 1 full turn)
with a slight upward pressure until the element
begins to further engage the header. With the prop-
er orientation now established, apply additional
pressure to seat the element in the filter header. You
should feel the element “pop” into place when prop-
erly seated.
NOTE: The element will only go on one way. Never use
excessive force when mounting the element to the
header.
5. Slide the quick change ring up over the element and
rotate counter clockwise until an audible click or
pop is heard. If you do not hear the click, you have
not rotated the ring far enough and the element is
not in the locked position. Another indication that the
ring is in the locked position is that one set (it does-
n’t matter which one) of arrows located on the out-
side of the ring should be located directly under the
air vent valve.
6. Open the fuel shutoff valve (lever in line with the
hose).
7. Open the air vent valve on the front of the filter head-
er until fuel emerges free of air bubbles. Then close
the air vent valve.
Secondary Fuel Filter: The Secondary Fuel Filter is a
spin-on cartridge type mounted directly to the engine.
Consult your engine operation manual for complete
information on service intervals and element changing
procedures.
